Recipe Ingredients

• OLIVE OIL: Olive oil is used for sauteeing the fresh garlic and onion and cooking the sausage. 
• ONION: Diced onion is sauteed until it’s caramelized, and it adds a lot of delicious flavor to this soup. 
• FRESH GARLIC: A few fresh cloves of garlic are minced and added to the soup for a fresh garlicky flavor.
• ITALIAN SAUSAGE: This sausage and spinach soup recipe uses spicy Italian sausage, which brings a little heat and a lot of flavor. You can choose to use a mild Italian ground sausage if you aren’t big on spice!
• SPICES & SEASONINGS: Dried basil and oregano, garlic powder,  and optional red chili flakes help enhance the flavor and savouriness of this soup. 
• CHICKEN BROTH: Chicken broth pairs well with the sausage and tomatoes and helps salt the soup while adding a ton of flavor from the ingredients already in the broth. 
• WHITE POTATOES: White potatoes are used in this spicy Italian sausage potato spinach soup recipe because they’re super creamy and add to the heartiness of the soup.
• SPINACH: Fresh spinach is used in this recipe, but you can use frozen if you prefer! Just like any other soup with spinach recipes, the spinach is tasteless, but it adds a nice color and texture to the dish and also provides a lot of nutrients. 
• SALT & PEPPER: These are used to enhance the overall flavor of the soup.

Alternative Ingredients

• Mild Sausage: If you’re not a fan of spice, then consider opting for a mild Italian sausage instead of spicy. Ground turkey is another great protein option! This soup will be just as full of flavor and delicious without the spice.
• White Beans: Consider adding white beans, like navy beans. They’ll add creaminess and heartiness to the soup. Be sure to drain and rinse the beans before adding them to the soup. 
• Kale: Kale is a popular substitution option for soup recipes with spinach as another leafy green that brings soup lots of color.
• Vegetables: Diced carrots and celery would be a great addition to the soup. They can be cooked the same time as you saute the onions.
• Pasta: Substitute the carbs with pasta noodles instead of potatoes! Some popular options are tortellini and gnocchi.

Step-by-Step Instructions

1. Sautee: In a large pot on medium heat, add the olive oil and cook the onions until they’re soft and translucent, about 10 minutes. Add the minced garlic and cook for 1 more minute. Push the onions and garlic to the sides of the pot and add the sausage. Cook the sausage for about 5 minutes, breaking it down into crumbly pieces.
2. Add Seasonings: Add the garlic powder, oregano, basil, salt, pepper, and optional red chili flakes to the sausage mixture. 
3. Boil: Add the chicken broth and increase the heat to high. Once the soup starts to boil, carefully add the potatoes and continue to boil for about 10-15 minutes, or until a fork can easily poke through a potato. 
4. Serve: Remove the soup from the heat and add the spinach. Let the soup sit for 5 minutes before serving.

Storage and Leftovers 

For storage and leftovers, this soup should be transferred to an airtight container and stored in the fridge for up to 5 days or in the freezer for up to 3 months.
